I've recently been gifted a boat from a family member that has been sitting for about 3-4 years. It was running at one point and we took it out prior to putting it into storage. The engine is a Mercruiser 165 Chevy L6 serial number 5390935. The motor cranks but will not spark.
So far I've replaced the coil, distributor cap and rotor, I've cleaned the points as well. I have spark at the points but it will not make it down to the plugs. The only other idea I have is new plug wires but I feel like I would get some sort of spark from one of the wires as they aren't in that bad of condition. I'm at a little bit of a loss right now for what to do next and don't really want to keep throwing parts at the thing.
With the key on the coil gets about 6.5v, one weird thing I noticed is that with the key on the hour meter clicks. It also does it when I jump the coil + terminal directly from the battery with the key off. I've read that maybe that has something to do with the shift interrupter switch so I cleaned the contacts on that as well but I don't really know if that's related.
